Thanks for this Simon. I have 2 questions though:

1. Do I just have to add this code at https://trac.buddypress.org/attachment/ticket/1150/hook-to-stop-group-creation.diff in the bp-groups.php or do I have to edit the whole file? If I have to edit it, in what particular part of the file should I put the code?

2. The code in https://trac.buddypress.org/attachment/ticket/1150/restrict-group-creation.php will be used as a plugin right? and I will upload it in the plugins folder and activate it?

Thanks in advance for your response!
